Four pieces of wooden sticks A, B, C and D are placed along the length of 30 cm long scale as shown in Fig. Which one of them is 3.4 cm in length?
Length of A = (2.7 – 0.3) cm = 2.4 cm Length of B = (6.5 – 3.4) cm = 3.1 cm Length of C = (10.4 – 7.0) cm = 3.4 cm Length of D = (14.4 – 10.7) cm = 3.7 cm
so, thr wooden stick C corresponds to 3.4 cm.
A piece of ribbon folded five times is placed along a 30 cm long measuring scale as shown in Fig.
The length of the ribbon is between:
(a) 1.15 - 1.25 m
(b) 1.25 - 1.35 m
(c) 1.5 - 1.6 m
(d) 1.6 - 1.70 m
You are provided three scales A, B and C as shown in Fig. to measure a length of 10 cm.
For the correct measurement of the length, you will use the scale,
(a) A only
(b) B only
(c) C only
(d) Any of three scales
